Climate change and the crisis of natural ecosystems force us to completely rethink the approach to design. The built space is one of the most responsible actors for the impoverishment of the biosphere. The damage perpetrated to the environment up to now has triggered degenerative models and processes, which require urgent interventions. From this perspective, the project must no longer be simply sustainable for the future but capable of regenerating resources and ecosystems in order to keep social needs together with the integrity of nature.
